Ideal logic combi 30 - ignition lockout

[bassmonster]

Hi all,
Need your help one again please. Boiler is saying ignition lockout. Anything obvious I should be looking for? No heating or water.

Make sure there's gas on the meter!:teeth_smile:

Haha... Already checked... Pump proving and so is fan.. I've resistance on gas valve 4.15k...what should this be?

Is it sparking?

This one was rather odd. When I first got there, only the pump came on. So I took out the power leads to check for voltage and I was getting 240 volts, plugged the lead back in, turned off the boiler then on again and presto, fan starred to work. Then as stated in number post 3 checked resistance in gas valve as there was no spark. I then reset the boiler on the control knob and it came back to life..... Still don't know what the problem was though.... Could it have been poor connection on the power to the fan?
